[0002] Fried eggs are a common food, with high demand in the catering industry, especially in fast food and canteens. Currently, egg frying is mostly done manually, which suffers from problems such as high labor intensity, low efficiency, difficulty in controlling hygiene, and inconsistency in egg quality (such as doneness and appearance). Although some automatic egg frying equipment has been proposed, these devices typically suffer from complex structures, low reliability, and limited functionality (e.g., inability to automatically open eggs, handle eggs in different positions, or achieve independent time control for both sides), limiting their widespread application in actual production.

The second sensor component is provided on either the mounting plate or the second guide rail plate.

[0016] A method for using a fully automatic egg frying machine, comprising the following steps: Step 1: Egg supply and posture adjustment.

[0017] The conveyor chain in the egg-feeding module moves, transporting eggs from the egg-holding rollers forward. During transport, the posture of eggs at multiple stations is simultaneously adjusted via the engagement of driven gears and racks. When an egg reaches the very front of the upper part of the conveyor chain, its posture is detected by a vision module. If the vision module detects an angle between the egg's long axis and a preset direction, it controls the adjustment motor to rotate. Through the engagement of the drive and driven gears, the egg-holding rollers are actively driven to rotate and adjust the egg's posture.

[0018] Step 2: Open the egg and remove the shell.

[0019] The eggs, after being positioned correctly, are fed from the egg-feeding module into the egg tray of the cam-driven egg-opening module. The lateral movement unit moves the drive unit along the mounting bracket, and the second cam assembly engages with the second protrusion assembly, driving the pressing head to push the egg in the tray towards the closing egg-opening blades, cutting the eggshell. The first cam assembly engages with the first protrusion assembly, driving the first and second half-baskets to open, causing the two egg-opening blades to separate, completing the egg-opening process. The egg liquid falls into the frying egg area below. The drive unit continues to move, and with the first cam assembly engaging with the first protrusion assembly, the first and second half-baskets further open, allowing the eggshell to fall from the tray and enter the eggshell dropping channel.

[0020] Step 3: Frying the egg.

[0021] The egg mixture falling into the frying area is cooked by a double-sided asynchronous frying module. Based on the preset first frying time for the first side, the first frying component cooks the first side of the egg. After the preset first frying time is reached, the first drive unit pushes the egg down, flipping it over and placing it into the second frying component. Based on the preset second frying time for the second side, the second frying component cooks the second side of the egg. After the preset second frying time is reached, the second drive unit pushes the egg out.

[0022] Step 4: Hatching the eggs.

[0023] Once the eggs are fried, they are sent out through the egg outlet.

[0024] The beneficial effects of this invention are as follows: 1. High degree of automation: It integrates the entire process of egg feeding, posture adjustment, egg opening, frying to egg output, which significantly reduces labor costs and labor intensity and improves production efficiency.

[0025] 2. Automatic posture adjustment: Through the passive adjustment of the rack and pinion and driven gear, combined with the active fine adjustment of the front-end visual detection and the adjustment motor, the egg is ensured to be in the preset optimal posture before opening (such as the long axis being aligned with the direction of the egg-opening blade), which improves the success rate of opening the egg and the integrity of the egg liquid.

[0026] 3. Reliable Egg-Opening Mechanism: Utilizing a cam-protrusion driven egg-opening module, the structure is compact and the action sequence is reliable. First, the second cam assembly drives the pressing head to push the egg onto the closed egg-opening blades for cutting. Then, the first cam assembly drives the two half-plates (egg-opening blades) to separate, resulting in a smooth egg-opening action, a clean cut on the eggshell, and minimal damage to the yolk. The added locking and unlocking mechanism ensures that the pressing head will not accidentally reset before opening the egg, increasing the reliability of the operation.

[0027] 4. Asynchronous cooking on both sides: It adopts independent first and second egg-frying components, which are controlled by independent drive units respectively. It can realize different cooking times on both sides of the egg (such as single-sided frying, tender double-sided frying, and fully cooked double-sided frying), which meets diverse cooking needs and ensures consistent product quality.

[0028] 5. Modular design: The egg feeding, egg opening, and egg frying modules have clear structures, which facilitates manufacturing, assembly, and maintenance.

[0029] 6. Optimized Egg Storage and Feeding: The egg storage box features an adjustable outlet gap design, coupled with a peristaltic pump to control the egg feeding speed, accommodating eggs of different sizes and achieving orderly, single-row egg feeding. The extended frame design increases the amount of eggs stored at one time, improving the continuous operating time of the equipment. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0032] like Figure 1 As shown, see reference Figure 2 This invention provides a fully automatic egg-frying machine, mainly comprising a frame 1, and sequentially arranged on the frame 1 an egg-feeding module 2, a cam-driven egg-opening module 3, a double-sided asynchronous egg-frying module 4, an egg-shell discarding channel 5, and an egg-outlet gate 6. Eggs are fed into the egg-feeding module 2, and after posture adjustment, enter the cam-driven egg-opening module 3 for opening. The egg liquid falls into the double-sided asynchronous egg-frying module 4 for frying. Egg shells are discharged through the egg-shell discarding channel 5, and the fried eggs are sent out through the egg-outlet gate 6. The specific composition and function of each module are described below: Egg supply module Combination Figures 2-9 As shown, the egg supply module 2 includes a support 27, an egg storage box 28, a conveyor chain 21, a drive unit 23, a rack 24, an adjustment motor 25, and a vision module.

[0033] The support 27 includes a first upright plate 271 and a second upright plate 272 arranged opposite to each other. The lower ends of the two are connected by a base plate 273, and one side is connected by a sealing plate 274. A support plate 275 is provided in the middle of the lower surface of the base plate 273. An egg storage box 28 is installed on one side of the support 27.

[0034] The egg storage box 28 includes an egg storage frame 281 with openings at the top and bottom, the upper end of which is connected to the frame via a mounting plate 287; the mounting plate 287 has a slot, and its lower edge is provided with an annular support frame 288; an extension frame 289 passes through the slot and is supported by the support frame 288, and the upper end of the extension frame 289 is provided with an openable cover 2891 for adding eggs; one side of the egg storage frame 281 has a slope 2811, and a first adjusting plate 282 and a second adjusting plate 283 are longitudinally hinged at the lower opening, forming an elongated egg outlet gap 284 between them, and an egg outlet groove 2812 corresponding to one end of the egg outlet gap 284 is provided on the slope 2811; the first and second adjusting plates (282, 283) Below is a height-adjustable support 285 (such as a screw and nut). Below the first adjusting plate 282 is a peristaltic pump 286, which is used to fine-tune its position to control the width of the egg-out gap 284 so that the eggs can roll out in a single row in an orderly manner. The length of the first adjusting plate 282 is greater than that of the second adjusting plate 283. Both of them have a downward-folding guide edge at their free ends to facilitate the guidance of the eggs to the conveyor chain 21.

[0035] The conveyor chain 21 is mounted on the support 27 and includes a first chain belt 211 and a second chain belt 212, which are opposite each other and are provided with a connector 213. The drive unit 23 includes a drive wheel 231, a driven wheel 232 and a drive motor 233. There are two sets of drive wheels 231 and two sets of driven wheels 232, which are respectively matched with the first and second chain belts. The two drive wheels 231 are connected by a synchronous shaft 234 and driven by a drive motor 233. Multiple egg-carrying rollers 22 are arranged in parallel between the first chain belt 211 and the second chain belt 212.

[0036] The egg-carrying roller 22 includes a rotating shaft 221 and a roller body 222 sleeved on it. The outer surface of the roller body 222 has an annular egg-carrying groove 223 to support the eggs. One end of the roller body 222 is coaxially fixed with a driven gear 224, and the other end is provided with a counterweight 225 to balance the weight of the driven gear 224. The two ends of the rotating shaft 221 are rotatably connected to the connecting piece 213 through bearings, so that the egg-carrying roller 22 can rotate freely around its own axis.

[0037] The rack 24 is mounted on the bracket 27, located below the upper side of the conveyor chain 21, with its tooth grooves facing upwards. When the conveyor chain 21 moves, the driven gears 224 of the multiple egg-carrying rollers 22 located on the upper side will mesh with the rack 24. Since the center of gravity of an egg is usually biased to one end (blunt end), under the action of gravity, the long axis of the egg tends to adjust to a horizontal position naturally, but the direction is random. The meshing of the driven gears 224 and the rack 24 will generate a certain resistance. This resistance will cause the egg-carrying rollers 22 to rotate, thereby causing the eggs on them to roll, so that their long axis tends to be consistent with the length direction of the rack 24 (i.e., the preset conveying direction), thus achieving preliminary passive posture adjustment.

[0038] The adjustment motor 25 and the vision module are positioned at the very front of the upper side of the conveyor chain 21. The vision module (such as a camera) is used to detect the posture of the egg on the frontmost egg-holding roller 22 and determine the angle between its long axis and the preset direction (usually perpendicular to the plane of the egg-opening knife 312). If there is an angle, the vision module sends a signal to the controller to control the adjustment motor 25 to rotate. The drive gear 251 on the output shaft of the adjustment motor 25 meshes with the driven gear 224 of the frontmost egg-holding roller 22 (or indirectly meshes through an idler gear), thereby precisely driving the egg-holding roller 22 to rotate and adjusting the egg to the preset precise posture, preparing it for subsequent egg opening.

[0039] Cam-driven egg-opening module Combination Figures 10-17 As shown, the cam-driven egg-opening module 3 includes a first half-support 31, a second half-support 32, a drive seat 33, a mounting bracket 36, a transverse movement unit 37, and a drive plate 38.

[0040] The first half tray 31 and the second half tray 32 are respectively provided with egg-holding half grooves 311, which form a complete egg-holding groove when they are closed, for receiving eggs from the egg supply module 2; the first half tray 31 and the second half tray 32 are also respectively fixed with egg-opening knives 312, which come together when closed; the drive seat 33 is driven by the transverse unit 37 (such as a motor-driven lead screw and nut pair or a synchronous belt module) and can move horizontally along the mounting bracket 36; the drive plate 38 is fixed on the mounting bracket 36 and is located on one side of the movement path of the drive seat 33.

[0043] The second cam assembly 35 is used to quickly push the egg toward the egg opener 312; it includes an egg pressing head 351, a push plate 352, and a first return spring 353; one end of the push plate 352 is connected to the egg pressing head 351, and the other end is provided with a second cam 3521; a guide plate 332 is provided with a guide groove 3321, in which the push plate 352 is placed, and the cover plate 331 seals the top; the first return spring 353 provides the push plate 352 with elastic force toward the egg; the push plate 352... A locking block 3522 is provided, the upper part of which passes through the movable through groove 3311 on the cover plate 331. The upper part of the locking block 3522 is provided with a slot 3523. The middle part of the buckle 402 is rotatably connected to the cover plate 331 via a rotating shaft. One end of the buckle is provided with a third cam 4021, and the other end is provided with a protrusion 4022 that can cooperate with the slot 3523. This end is also connected to the cover plate 331 via a second return spring 4023, so that the protrusion 4022 tends to press down and engage with the slot.

[0044] The second protrusion assembly 40 includes a second protrusion 401 and a third protrusion 403 fixed on the drive plate 38; the second protrusion 401 is provided with a second driving inclined surface 4011; the third protrusion 403 is connected to the avoidance module 404; the avoidance module 404 includes an avoidance seat 4041 fixed on the drive plate 38, which is connected to the third protrusion 403 through a rotating shaft 4042, a torsion spring 4043 is provided on the rotating shaft 4042, and a limiting groove 4044 is provided on the avoidance seat 4041; initially, under the action of the torsion spring 4043, the protrusion 4031 of the third protrusion 403 passes through the limiting groove 4044 and is in a fixed rigid state, which cannot be easily pushed.

[0045] The work process is as follows: (a) Egg receiving position (closing, locking): The drive seat 33 is located in the rightmost initial position; the first cam 3411 is not in contact with the first protrusion 391. Under the action of the elastic element 346, the first and second half trays (31, 32) close together to form an egg tray groove; the latch protrusion 4022 of the buckle 402 is engaged in the slot 3523 of the locking block 3522 under the action of the second return spring 4023, which firmly locks the push plate 352 in the rearmost retracted position, and the egg pressing head 351 does not contact the egg; the egg with the adjusted posture is sent from the egg supply module 2 into the closed egg tray groove; (b) Moving to the egg-opening position (keeping closed and unlocked): The lateral movement unit 37 drives the drive seat 33 to move to the left; when approaching the egg-opening position, the third cam 4021 on the latch 402 contacts and presses the third protrusion 403 in a rigid state; as the drive seat 33 moves to the left, the third protrusion 403 forces the latch 402 to rotate, the latch protrusion 4022 is lifted from the latch groove 3523, and the push plate 352 and the egg-pressing head 351 are unlocked; (c) Egg-opening location (egg-opening): such as Figure 12 As shown, the drive seat 33 reaches the preset egg-opening position; the push plate 352 is instantly ejected to the left under the elastic force accumulated by the first return spring 353, which drives the egg-pressing head 351 to strike the egg at high speed, causing it to violently hit the two egg-opening blades 312 that are brought together, cutting the eggshell; the egg liquid falls from the crack into the first fried egg tray 421 below; at this time, the push plate 352 and the egg-pressing head 351 are in the forward extended position; (d) Moving to and reaching the position where the eggshell is dropped (push plate resets, half-opening): After the egg is opened, the drive seat 33 continues to move to the left, heading towards the eggshell dropping position. Initially, during the initial movement, the second cam 3521 on the push plate 352 contacts the second drive ramp 4011 of the second protrusion 401. As the drive seat 33 continues to move to the left, the second protrusion 401 pushes the second cam 3521 to the right via the second drive ramp 4011, thereby pulling back the push plate 352 and the egg-pressing head 351. When the push plate 352 returns to its final retracted position, the latch protrusion 4022 of the latch 402, under the action of the second return spring 4023, again engages with the slot 3523 of the locking block 3522, locking the push plate 352. Simultaneously, as the drive seat 33 moves to the left, the first cam 3411 begins to contact the first drive ramp 3911 of the first protrusion 391. The ramp forces the push rod 341 to move to the right, pushing the first and second drive rods (344, 343) through the first and second connecting rods (342, 343). 345) Overcoming the tension of the elastic element 346, it swings outward, thereby driving the first half tray 31 and the second half tray 32 to gradually open outward; when the drive seat 33 reaches the leftmost eggshell dropping position, the first cam 3411 moves to the specific position of the first protrusion 391, so that the first and second half trays open to the maximum angle, the egg tray groove is fully opened, and the two half eggshells fall out of the egg tray groove under the action of gravity and are discharged through the eggshell dropping channel 5; (e) Return to Egg-receiving Position (Reset, Avoidance, Preparation for Next Cycle): The drive seat 33 returns to the right from the shell-dropping position; when returning near the egg-opening position, since the push plate 352 is locked in the retracted position, the third cam 4021 of the latch 402 will contact the third protrusion 403 again; at this time, since the drive seat 33 moves to the right, the third protrusion 403 is subjected to a force to the left, which can overcome the torque of the torsion spring 4043 and rotate a small distance towards the limiting groove 4044 in the avoidance seat 4041 to achieve "avoidance" without blocking the passage of the latch 402 and the drive seat 33; the drive seat 33 continues to move to the right back to the initial position on the far right, the first cam 3411 disengages from the first protrusion 391, and under the action of the elastic element 346, the first and second half-feeders close again; at this point, a complete working cycle ends, the equipment returns to the egg-receiving position, in a closed and locked state, ready to receive the next egg; Compact structure and high integration: By integrating core functions such as egg opening, egg pushing, and shell dropping into a single drive unit that moves as a whole under the action of a lateral movement unit, and driven sequentially by a fixed drive plate through the cooperation of protrusions and cams, the equipment structure is greatly simplified, the number of independent drive components is reduced, and the control complexity is lowered; Precise action sequence and reliable egg opening: Utilizing mechanical timing control with cam-protrusion cooperation, the entire action sequence is strictly guaranteed, avoiding action interference caused by electrical control timing errors, thus improving the success rate of egg opening and the integrity of the egg liquid; Convenient maintenance and strong adaptability: The main transmission components are mechanical structures with good durability. By adjusting the shape, position, and angle of each protrusion on the drive plate, process parameters such as egg opening force and locking timing can be easily adjusted to adapt to poultry eggs of different sizes or hardness.

[0046] Double-sided asynchronous fried egg module Combination Figures 18-20 As shown, the double-sided asynchronous egg-frying module 4 includes a vertically mounted mounting plate 41; the front side of the mounting plate 41 (the side closest to the cam-driven egg-opening module 3) has a first egg-frying component 42 and a second egg-frying component 43 arranged vertically; the first egg-frying component 42 includes a first egg-frying tray 421 and a first egg-pushing spatula 422, and the second egg-frying component 43 includes a second egg-frying tray 431 and a second egg-pushing spatula 432; the back side of the mounting plate 41 has a first drive unit 44 and a second drive unit 45 vertically distributed, which drive the first egg-pushing spatula 422 and the second egg-pushing spatula 432 to move through a linkage or slide rail mechanism, respectively; the first drive unit 44 and the second drive unit 45 can be a motor-driven lead screw module, cylinder or linear motor, etc.

[0047] A base plate 46 is fixed on the mounting plate 41, and a first upright plate 47 is fixed on the base plate 46. A first drive unit 44 is mounted on the first upright plate 47, and a second drive unit 45 is mounted on the base plate 46. A second upright plate 48 and a third upright plate 49 are also fixed on the base plate 46. The second upright plate 48 is provided with a first guide rail plate 481 for guiding the movement of the first egg-frying component 42, and a first sensor component 482 is provided on the first guide rail plate 481 for detecting the position of the first egg-pushing spatula 422.

[0048] Workflow: First side cooking: The egg is cracked into the first egg tray, and the control system heats it according to the preset first side cooking time.

[0049] Flipping action: When the first side is cooked, the control system starts the first drive unit, which drives the first egg-pushing spatula to move, lift the egg from the first egg tray and flip it so that it falls onto the second egg tray below. The first sensor component provides real-time feedback on the position to ensure that the action is in place.

[0050] Second side cooking: The egg begins to cook on the second omelet tray for the second side. The key point is that the cooking time for the second side can be set independently of the first side. For example, if you want one side tender and the other crispy, set a shorter time for the first side and a longer time for the second side.

[0051] Egg removal action: When the second side of the egg is cooked, the control system activates the second drive unit, which drives the second egg pusher to move and push the cooked egg out of the second egg tray, completing the entire egg-frying process. The second sensor component ensures that the pushing action is accurate.

[0052] Through the above independent control, the frying parameters (mainly time) of the two sides can be combined arbitrarily, thereby achieving personalized customization of the fried egg's texture.

[0053] A method for using the above-mentioned fully automatic egg frying machine includes the following steps: S1: Egg supply and posture adjustment; When the equipment is started, the drive unit 23 drives the conveyor chain 21 to move step by step; the eggs roll out in a single row from the egg outlet gap 284 of the egg storage box 28 and fall onto the egg tray 223 of the egg tray roller 22 for conveying; during the conveying process, the driven gear 224 of the egg tray roller 22 meshes with the fixed rack 24 to generate rotation, so that the long axis direction of the eggs is initially adjusted to be close to the conveying direction under the action of gravity; when the eggs move to the front end of the conveyor chain 21, the vision module takes a picture of them for detection; if there is an angle between its long axis direction and the preset precise direction, the controller starts the adjustment motor 25, which drives the driven gear 224 of the egg tray roller 22 through the drive gear 251, causing the eggs to rotate to the precise posture; S2: Open the egg and discard the eggshell; The eggs, after being adjusted in position, are fed into the egg tray of the cam-driven egg-opening module 3, which is in the closed state; the transverse unit 37 is activated, driving the drive seat 33 to move along the mounting bracket 36. First, the second cam assembly 35 cooperates with the second protrusion assembly 40 to drive the egg pressing head 351 to push the egg towards the two closed egg-opening blades 312 to cut the eggshell; at the same time, the buckle 402 automatically locks the push plate 352. Next, the first cam assembly 34 cooperates with the first protrusion assembly 39 to drive the first half tray 31 and the second half tray 32 to open, the two egg openers 312 separate, the egg is opened, and the egg liquid falls into the first fried egg tray 421 below. As the drive seat 33 continues to move, the first and second half trays are further expanded, and the eggshells fall off the egg tray grooves and are discharged through the eggshell discharge channel 5. When the drive seat 33 returns, the third protrusion 403 triggers the latch 402 to unlock, and the egg pressing head 351 is reset under the action of the first reset spring 353. S3: Steps for frying an egg; Egg mixture falls onto the first egg-frying tray 421, and the first egg-frying component 42 fries its first side. The first egg-frying tray 421 and the second egg-frying tray 431 are heated by a heating device (such as an electric heating element or an electromagnetic heater, not shown in the figure). The controller keeps time according to the preset frying time for the first side. When the time is up, the first drive unit 44 is activated, driving the first egg-pushing spatula 422 to lift the fried egg and push it away from the edge of the first egg-frying tray 421. The egg flips over and falls into the second egg-frying tray 431 below. The second egg-frying component 43 fries the second side of the egg, and the controller keeps time according to the preset frying time for the second side. When the time is up, the second drive unit 45 is activated, driving the second egg-pushing spatula 432 to push the fried egg out. S4: Egg hatching; The fried egg, pushed out by the second egg-pushing spatula 432, is sent out of the equipment through the egg-exit gate 6, completing the entire egg-frying process; Through the above-mentioned integrated automatic design, this invention realizes continuous, efficient, and high-quality automated production from raw eggs to finished fried eggs, which is particularly suitable for centralized processing scenarios in the catering industry.
